Abstract.
Possibilities to decrease the field intensity in semi-shadow zone of the field
diffracted over the edge of half-plane are dicussed. For that purpose a
semi-transparent edge is treated. Both qualitative Kirchhoff analysis and strict
numerical optimization are performed. It is shown that semi-transparent edge
with reactive impedance allow for significant shadowing improvement versus perfect
conductive one. Results are applicable to electromagnetic compatibility,
jamming protection and multipath error mitigation.
Key words:
Half-plane diffraction, semi-transparent sheet, semi-shadow zone.
